“The speedrun founder community is amazing.
I've been building consumer products for over a decade at ByteDance and Google, and have never seen such a high concentration of talent and high-retention products. The founder journey can be lonely, but having a support network of other high-caliber founders is so invaluable.”
Lucky Zhang
Founder and CEO of Sekai
“Altera wouldn't have been the same without speedrun.
Speedrun was an incredible experience that reinforced in us the importance of velocity—shipping and learning quickly. We leveraged the program to iterate our way toward PMF faster. And we love working with the speedrun team—they had a solution for all of our questions from cloud credits, to early access to new AI model releases, to intros to key decision-makers at Google, Meta, and X. Jon Lai and the team have grown into some of our closest friends and advisors.”
Robert Yang
Founder and CEO of Altera
“We are where we are today because of speedrun.
Speedrun’s involvement since leading our pre-seed round has been transformational for k-ID. They’ve been instrumental in securing top talent, including our CTO, connecting us with vital early design partners, and offering sharp strategic guidance on everything from pricing to fundraising—paving the way for our oversubscribed Series A.”
Kieran Donovan
Founder and CEO of k-ID
“Joining speedrun was a great decision for Echo Chess.
We received strong support from the team, accelerating our path to PMF. They also introduced me to the investor who eventually led my next round. Most importantly, I loved being a part of an inspiring community full of smart, ambitious founders working on hard problems.”

Founder and CEO of Echo Chunk
